Please help identify this boat

[pvb]

In 1967 with my New Shetland 535 with two 33 HP Evinrude's I attempted to go round South Stack after leaving Holyhead. And one of the engines packed up.
I would say that boat is not Seaworthy. Even if you put a couple of outboards on the back you should only stick close to shore.

I'd agree, it's not a seagoing boat at all. Great on a river, or possibly in an estuary, but that's about it. In a previous life I once had a Shetland 570 with a 40hp outboard, and that certainly wasn't a sea boat.

Would the problem be the lack of power rather than the hull? I thought the 570 was used for offshore racing.

I doubt that would work for a double curvature window, what they do is make a former using wood and filler to the correct shape, then fill a tray with Glycol and heat it from underneath, when done correctly the sheet goes floppy and can be dropped onto the former, but get it too hot and it will cloud up, it needs careful experimenting with the temperature, if you can DIY it, it will save you a big wedge.

From the picture of the restored one it's not clear they are double curvature; a lot of heating will be needed nonetheless. Laminating a mould in-situ will be easiest, 3-4 layers of 1.5mm ply screwed and glued to the openings. There are plenty of guides to heat-forming acrylic on yootoob.

Racing people do all sorts of strange things.

It is not a rib. My 535 is an estuary boat and inshore with suitable conditions, travels at 30 knots comfortably.

The intention is to take it just on inland water e.g the Norfolk Broads. Doing some research, the Dorsetts look quite nice done up- not sure we will get her to that standard though!

Windows do seem to be an issue, I may well look to get quotes to see as not sure I back myself to do a DIY job. We are on a small budget, though. Thanks to all for suggestions.

Will keep people posted

the 570 is happiest with 70-90hp, and is a good boat at sea.
I've been 50 miles out from Milford Haven on the right day in my Family Four 70hp amd felt safe. Some days I've been out in snotty conditions with green waves coming over the windscreen and not felt that the boat wasn't going to get me home

there are two types of windows, polycarbonate and acrylic, i can't remember which is which, but one is really scratch resistant but needs heat for even the slightest curve, the other bends easily but has a much softer surface and is prone to scratching.

A first try to make a template with soft cardboard or very thin ply will answer the question about single or double curvature. It will need a very big panel to accommodate the area that that window covers. Don't assume that each side is the same shape. Just flipping over the template may not produce a true fit.
If that exercise shows it to be a double curvature you need to think hard about that.
A cruising area with a 4 mph speed limit may not suit a hull with a planing profile. Just hanging a 9 hp Honda on the back may not produce an easy boat to handle.

true that planing hulls may wander a bit at very low speeds, but they are easier to handle with small outboards running high revs than an a large outboard on tickover. My Shetland F4 can blow around like a crisp packet on a puddle in a breeze and low revs on the main engine, but is much better with the 4hp aux motor.
It would be a shame to not see a heritage boat on the Broads just because it isn't perfect. Most things about boats are compromises.

It is not a rib. My 535 is an estuary boat and inshore with suitable conditions, travels at 30 knots comfortably.

And will do across the channel on the right forecast as will drums. Avon tenders. Canoes. Wooden pallets. Swimmers. Most of my motor boats and ribs I found early 20kts to be comfortable.

The main factor governing speed/comfort is the sea state.

I'd agree. Fine in sheltered water in good weather, but I'd scurry home if the wind starts building

 

[Jim@sea]

Was it for sale somewhere else, listed as a Shetland, then?

Would I be wrong in that even if it was a Private Seller if it was advertised incorrectly you would be entitled to a refund.

Good luck with that!

I'd agree, we have a 570 with 70hp planes great, even on the rough stuff. Takes some work in heavy seas, but the 570 is a good solid and stable boat. Admittedly stay in relatively sheltered waters but have been over to Mull a few times. For its size I would say one of the best.
